Mozilla: IonMonkey leaks JS_OPTIMIZED_OUT magic value to script

The IonMonkey just-in-time JIT compiler can leak an internal JSOPTIMIZEDOUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash. This vulnerability affects Thunderbird...

Denial Of Service (DoS)

Firefox, Firefox ESR and Thunderbird are vulnerable to denial of service attacks. A remote unauthenticated attacker could exploit the vulnerable Window Resizing component when re-computing layout for a "marquee" element during window resizing where the updated style object is freed while still in...

Denial Of Service (DoS)

Mozilla Firefox is vulnerable to use-after-free vulnerability. This occurs when manipulating ranges in selections with one node inside a native anonymous tree and one node outside of it resulting a potentially exploitable crash...

Out-of-bounds Write

Thunderbird, Firefox ESR, and Firefox are vulnerable to out-of-bounds write. ClearKeyDecryptor function can be exploited by a remote attacker to cause out-of-bounds write via decrypting some Clearkey-encrypted media content. This may lead to writing of arbitrary data within memory, resulting in a...

Buffer Overflow

Thunderbird, Firefox ESR, and Firefox are vulnerable to buffer overflow. An unauthenticated remote attacker could exploit the flaw in WebGL with the use of triggerable by web content, resulting in a potentially exploitable crash...

Denial Of Service (DoS)

firefox is vulnerable to use-after-free vulnerability. Manipulating DOM subtrees in the Editor may result in potentially exploitable crash...

Denial Of Service (DoS)

Mozilla Firefox is vulnerable to buffer overflow vulnerability. This is due to memory allocation issues when handling large amounts of incoming data resulting a potentially exploitable crash...

Arbitrary Code Execution

mozilla firefox is vulnerable to Heap-based buffer overflow vulnerability. Remote attackers can execute arbitrary code via directional content in an SVG format graphics resulting in a potentially exploitable crash...

Use-After-Free

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox. Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with...

CVE-2019-9795

A vulnerability where type-confusion in the IonMonkey just-in-time JIT compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. This vulnerability affects Thunderbird 60.6, Firefox ESR 60.6, and Firefox 66...

CVE-2019-9791

The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time JIT compiler and when the constructor function is entered through on-stack replacement OSR. This allows for possible arbitrary...

Type confusion

The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time JIT compiler and when the constructor function is entered through on-stack replacement OSR. This allows for possible arbitrary...

Design/Logic Flaw

A use-after-free vulnerability can occur when a raw pointer to a DOM element on a page is obtained using JavaScript and the element is then removed while still in use. This results in a potentially exploitable crash. This vulnerability affects Thunderbird 60.6, Firefox ESR 60.6, and Firefox 66...

Design/Logic Flaw

A use-after-free vulnerability can occur while playing a sound notification in Thunderbird. The memory storing the sound data is immediately freed, although the sound is still being played asynchronously, leading to a potentially exploitable crash. This vulnerability affects Thunderbird 60.5...

CVE-2019-9795

A vulnerability where type-confusion in the IonMonkey just-in-time JIT compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. This vulnerability affects Thunderbird 60.6, Firefox ESR 60.6, and Firefox 66...

CVE-2019-9795

A vulnerability where type-confusion in the IonMonkey just-in-time JIT compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. This vulnerability affects Thunderbird 60.6, Firefox ESR 60.6, and Firefox 66...

CVE-2018-12401

Some special resource URIs will cause a non-exploitable crash if loaded with optional parameters following a '?' in the parsed string. This could lead to denial of service DOS attacks. This vulnerability affects Firefox 63...

Mozilla: Type-confusion in IonMonkey JIT compiler

A vulnerability where type-confusion in the IonMonkey just-in-time JIT compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. This vulnerability affects Thunderbird 60.6, Firefox ESR 60.6, and Firefox 66...
